DAVID S. KENNEDY, 0F BROOKLYN, NEW YORK, ASSIGNOR TO MERGENTHALER, LINOTYPE COMPANY, A CORPORATION OF NEW YORK.

TYPOGRAPHICAL MACHINE.

T all whom it may concern:

Be it known that I, DAVID S. KENNEDY, a citizen of the United States, residing at Brooklyn, in. the county of Kings and State of New York, have invented certain new and. useful Improvements in 'lypographical li lachines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographical. ma .:hines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 436,532, to O. lvlergenthalcr, wherein metal slugs or type bars are cast in a mold, and then ejected therefrom between two trimming knives, which insure the parallelism of their opposite side faces and the exact thickness required, one of the knives being adjustably mounted in order that the distance between them may be varied at will. In my previous Letters Patent, No. 1,002,281, the adjusting means are shown as comprising a rotary sector plate provided with adjustable studs to move the knife slide, and an actuating handle by which the sector may be turned to the desired position, and my present improvements are shown more particularly in connection with this specific mechanism. It frequently happens in the use of these devices that after certain adjustments of the knife, the actuating handle projects at the front of the machine in such manner as to interfere with the operators movements and his free manipulation of the parts.

It is one of the purposes of my invention to obviate this dilliculty, by permitting the detachment of the handle and its movement out of the way, without affecting the existing knife adjustment; and similarly, I pro vide means whereby the handle may be operatively connected to the adjusting means at any one of a plurality of points, thereby materially increasing the convenience and efiiciency of the device. I also provide means whereby the handle may be securely locked in all positions, thereby preventing its accidental disengagement and the derangement of the parts. These and other features of my invention will be described in the specification and finally pointed out in the claims.

In the accompanying drawing, I have shown my invention in preferred form and by way of example, and as applied to the Specification of Letters Patent.

Application filed November 29, 1913.

Serial No. 803,687.

specific style of machine already mentioned, but obviously many changes and variations may be made therein, and in its mode of application, which will still be comprised within its spirit. loner-ally speaking, I de sire it to be uiulerstood that I do not limit myself to any specific form or embodiment, except in so far as such lin'iitations are specified in the claims.

Referring to the drawii'igz Figure 1 is a side elevation, partly l)l.'0l\'0ll away, of the knife block, etc., having my improvements applied thereto; Fig. 2 is a section taken substantially on the line 2-2 of Fig. 1; Fig. I) is a section taken substantially on the line 3-3 of Fig. 1 and Fig. -fl, is a detached pcrspecl'ive of the indicator plate.

As in my said Letters Patent, the knife A is adjusted to dillercnt positions by the adj listing member or rotary sector B provided at its side with a series of studs B The adjusting movement effected by the handle which simultaneously moves the indicator plate l having the pointer E with relation to the scale F mounted upon the fixed plate F. The handle 0 is provided with longitudinally movable pins G passing therethrough and adapted to engage the staggered locking holes F formed in the plate F, and also with the pivoted operating lever l), the farther end of which I) engages the heads of the pins G, sothat when the lover I) is actuated, the pins will be withdrawn from the holes F. A spring C is interposed between the lever D and handle G to hold the former in its normal position, and the lever is further provided with leaf springs l) bearing upon the heads of the pins G, to hold the latter in proper relation to the end D of the lever, and to permit a pin to yield in the event of its failure to engage with a locking hole F as indicated by dotted lines in Figs. 2 and 3. The parts so far described, in construction and mode of operation, are sul'istantially the same as those presented in my said Letters Patent, except as hereinafter pointed out.

In the present instance, the handle C, and the parts carried thereby, are relatively movable with reference to the indicator plate E and sector B, which latter are connected so as to rotate together. The plate E is formed with holes E corresponding in number and locationto those of the holes F inthe fixed plate F, and the plate E is located between the handle C and the plate F (see Figs. 2 and so as to permit the pins G to pass through the holes E and engage the locking holes F at the will of the operator.

The operation of my improved devices knives ad ustable laterally toward and from will now be readily understood. Assuming the adjustment and locking of the. parts in the extreme position indicated in Fig. 1, the handle C would occupy the dotted line position. In order to shift the handle out of the way, the operating lever D is moved against the force of the spring C and thereby the pin. or pins G are withdrawn from both the locking holes F and the holes E of the plate E. The handle C may now be moved to its full-line position, without disturbing the knife adjustment, orthe relation of the pointer E to the scale F The release. of the lever D then permits the spring 0 to act and the consequent engagement of a pin G with another hole E of the plate E and: another locking hole F thereby relocking the member 13' and indicator in their original position. Similarly, it will be seen that by the means described the handle C may be connected to the plate E and sector B in substantially any desired" angular relation, thereby materially increasing the convenience of adjustment.

In order to prevent the accidental disengagement of the locking pin G, and thus to insure the permanence of the knife adjustment, I provide the handle G with a pivotally mounted catch H, so located thereon. that it may be interposed between the handle and the operating lever D and prevent the movement of the latter, as shown in Fig. 2, orv be turned to inoperative position. to permit the free actuation'of: the lever D, as shown in Fig. 3.

As previously stated, I have shown my invention only in preferred: form and by way of example, and as appliedito a specific style of machine; but obviously many modifications and alterations therein, and in its mode of adaptation, will suggest themselves to those skilled in the art, without departure from its scope.

Having thus described my invention, its constructlon and mode of operatlon, what I claim and desire to secure by Letters Patent of the United States, is as follows l; A slug-trimming mechanism comprise ing, in combination, a. pair of. trimming knives adjustable laterally towardiand from each other, and aishiftable handle for so adjusting the knives, the said handle being movable at will from its shifted position without disturbing the adjustment of the knives.

2. A. slug trimming mechanism compris ing, in combination, a pair of trimming knives adjustable laterally toward and from each other, a shiftable handle for so adjusting the knives and movable at will from its shifted position without disturbing the adjustment of the knives, and means for locking the handle in its new position.

3. A. slug trimming mechanism comprising, in combination, a pair of trimming each other, a shiftable handle to efiect the adjustment thereof and movable from its shifted position without disturbing such adjustment, and means for locking the knives in adjusted position.
